Overview of this book

With the increased demand for computer systems and the ever-evolving internet, network security now plays an even bigger role in securing IT infrastructures against attacks. Equipped with the knowledge of how to find vulnerabilities and infiltrate organizations through their networks, you’ll be able to think like a hacker and safeguard your organization’s network and networking devices. Network Protocols for Security Professionals will show you how. This comprehensive guide gradually increases in complexity, taking you from the basics to advanced concepts. Starting with the structure of data network protocols, devices, and breaches, you’ll become familiar with attacking tools and scripts that take advantage of these breaches. Once you’ve covered the basics, you’ll learn about attacks that target networks and network devices. Your learning journey will get more exciting as you perform eavesdropping, learn data analysis, and use behavior analysis for network forensics. As you progress, you’ll develop a thorough understanding of network protocols and how to use methods and tools you learned in the previous parts to attack and protect these protocols. By the end of this network security book, you’ll be well versed in network protocol security and security countermeasures to protect network protocols.

Typical suspicious patterns

Viruses, Trojans, worms, ransomware, and other types of malwares can be executed on endpoints—this is what standard endpoint security software and systems protect against, but there are two major problems with this.

The first problem is that when one of these malwares gets to your end device, it is being fought at the gate—that is to say, you fight it when it has already reached your devices. In most cases, you will win the war, but if you do not, the enemy is in your home.

The second, more common problem is that not all devices can be protected with standard endpoint security systems. You cannot install anti-virus on an IoT sensor; some of the software that is used is open source, which has no safety guarantee, and although the network access control (NAC) system approves users when they connect to the network, you can never be 100% sure that a private phone or laptop is not infected.

For this reason, one of the new concepts in...
